Roast the roasted gram dal (yes, it has to be roasted again,though the name says roast gram dal) for about 3 and 1/2 minutes, till a nice aroma comes and the colour starts to change. Let it cool completely.
Powder the roast gram dal very finely. Powder the cardamom seeds along with the sugar very finely.
Sieve the powdered gram dal and sugar to a deep and wide bowl. Add the ghee gradually into the mixture and mix well.
Shape the laddus when the mixture is warm itself. Roll it in your palms tightly. If its crumbling while rolling add a little more melted ghee.
It should be tightly rolled,otherwise it will break.
Store it in an airtight container
Notes
I got around 14 small size laddus from the above qty. Add 1/4 cup ghee first and and if the laddus are crumbling add more ghee. You can also fry some cashews in ghee and add to the powdered sugar and gram.You can store it in an airtight container @ room temp for a week or so.
